<p>PURPOSE:To prevent warping of clamp, by moving a wire supporting means and a clamp supporting means in predetermined direction when the clamp is compressed thereby allowing axial elongation of the wire. CONSTITUTION:The tip of an anchor clamp C mounted at one end of a wire W is secured through a clamp supporting means 3. The wire W is supported approximately in horizontal through a wire supporting means 2 facing with the clamp supporting means 3. The clamp supporting means 3 is arranged movably and resettably to original position on a base 1 so that axial displacement of the clamp C is allowed. The wire supporting means 2 is arranged movably in the axial direction of the wire W with respect to the base 1. A hydraulic compression unit 4 movable along the anchor clamp C is arranged on the base 1 between the clamp supporting means 3 and the wire supporting means 2. When the clamp C is compressed, the wire supporting means 2 and the clamp supporting means 3 move to allow axial elongation of the wire W.</p> |
